Trying to figure out what I found, can anyone help?

I have not measured the exact size yet but from the overall size and looks, is it possible that this teeth is from megalodon? Or just a big great white teeth?

Hi, I recently bought this tooth from a friend, but I am uncertain which species it belongs to. The root is very thin with great white characteristics, but the lack of serrations on the blade is more like a mako. My best guess is that it is a Giant White Shark (Charcharodon Plicatitis). It measure 2.75 inches. The last 2 photos show the tooth in comparison to a Great White tooth on the right side and a Mako Shark tooth on the left side of the tooth in question. What do you believe it is? Thank you for helping me out.

Hello, I've had a shark's jaw for quite some time now and I'm curious to know what type of shark it belonged to. Can anyone please give me some clues based on the photos I've attached? I'm a newbie and fossil neophyte. Thank you very much in advance, Luc

Hello I have just bought through an online auction my first fossil, supposedly a Carcarodontossaurus tooth but I'm in doubt if it is real. Can you guys help me analyzing it's authenticity? Description and pictures follows below: LOCATION: Taouz, Errachidia Province, South Morocco GEOLOGICAL FORMATION: Ifezouane Formation, Red Sandstone Beds, KemKem Basin Size and weight: 50.5 mm • 1.99 in, 13g DESCRIPTION Finest grade Carcharodontosaurus tooth. It is complete, from the base to the tip. Its lateral serrations are deeply developed. This tooth has been stabilized on its surface by Paraloid B-72 to ensure its stability and consistency. This process does not affect neither the color nor any of the characteristics. It simply makes the specimen better preserved in the long term. It has small fractures that have been glued but no restored or fabricated at the lower part of the tooth.

Hi there! My partner took a trip to San Francisco and I asked him to bring me back a shell(I collect shells) and he comes home with this! I'm absolutely stumped! No idea what this could be. Input?

Hi below are some gorgeous teeth found this week on a Cape Town beach. Please note not all teeth were found by me - some were bought from other lucky local hunters. I suspect the second large tooth might be a transitional Mako feel free to let me know what you think.Feel free to message me if you want any more info on the teeth. (Please excuse rusty calipers)

Hi! I'm new to fossil hunting and I went to the Calvert Cliffs formation in Maryland this week. I collected these fossil looking pieces, but I'm having trouble identifying them and whether or not any are actual teeth (shark or other animal) or teeth fossilized in something. Any help would be appreciated!

Recently I aquired this Carcharodon tooth from Sacaco, Peru whose serrate conditions seems a bit peculiar to me. I can't really decide whether or not this tooth is from a late-stage hubbelli or an early carcharias. The serrations seem to wear/taper off just short of the tip on one side and abruptly end near it on another, and some (although not all) of the serrations appears to be angled in a way, although I suspect some may be due to wear. My thoughts on the serrations keep seesawing in my head. Would this tooth better represent a late-stage hubbelli or a carcharias? Thanks for any and all answers. Lingual

Hello alll! Ive been a fossil hunter for years and recently dug up this Great White tooth at a site close to where I live here in Cali. Was wondering how big is the largest great white tooth ever found? Thanks.

Hello! This seems like a rather homey website and I've just recently shown an interest in collecting fossils. I actually happened to have purchased my first one earlier today and was hoping to have it verified to see if it's fake or not. It's relatively damaged, but still a neat looking tooth. I was told it was found off of Cape Cod, and i didn't purchase it for much (only 25$) so it's not a big loss if it happens to be a fake. I attached a few photos to view. My biggest concern is how smooth the actual tooth is. Thank you for all the help in figuring out if this is genuine!

Bought from a antique fair and was told it was a mosasaurus from north Africa but not sure , was wondering if a good idea to disassemble and rebuild to a more natural for ? Regards Nathan

Our final stop in the Shark program is of course the giant Sharks of the Miocene. We wrap our adventure through the timeline of shark evolution by giving the kids what they expect to see, big shark teeth. Truthfully, we do not have many large shark teeth. I went for interesting teeth not big teeth but we have a few that will grab the kids attention. We give a very brief introduction to the giant sharks with a 2 inch Otodus tooth. We can spend too much time on Otodus or the ancestors of Megalodon as it just do not have time ( plus we do not have teeth from Auriculatus, Angustidens, or Chubutensis). After that brief bit, we ask the kids a question.... What shark is the ancestor of the modern Great White ? We give the kids a chance to answer that question for themselves by connecting them to the sharks that swimming in the ocean off the coast of California 12 million years. I want to explore the origins of the most well known modern shark and connect them to the fossil rich area just 6 or so hours south of where they live so we journey to Sharktooth Hill to finish the program. Isurus planus was a fairly large shark and probably reached lengths of over 20 feet. I have not found a lot of material about planus but I would think that based on tooth size, 20 feet seems possible. I have seen 2 inch planus teeth though I have nothing that big myself. We also show the kids a couple Isurus desori teeth only to mention that they MIGHT be related to modern Short-fin Makos. We then jump into another species that is present at STH and the one the kiddos will be most familiar with, Megalodon. This is obviously a super important species to talk about because it is the most popular prehistoric shark. It is the T-rex of sharks. Biggest teeth of any shark found so far. Most likely the largest shark ever and quite possibly the largest fish. They ate whales. They were also common and the apex predator in the worlds oceans during their time. We do not know what they look like but my son is working on his version of Megalodon and it has elements of a basking shark to it along with the traditional Great White like appearance. I will tell the kids that for a long time, Megalodon was thought to be the ancestor of great whites but science has uncovered another possible contender for being the ancestor of great whites. Carcharodon hastalis was a large shark that probably reached 30 feet in length. They had large teeth and were probably fast swimming ambush predators. I remember reading somewhere, that evidence existed from STH that the Broad-tooth White Shark hunted early pinnipeds from underneath, just as modern white sharks do. I can not remember where I read that and I want to track that down again to verify before saying that to kids. Anyway, we explain that they were probably very similar in appearance to great whites and filled a similar ecological role. I will add that transitional teeth have been found that are a pretty conclusive link the chain of white shark evolution but we want them to check out the teeth and judge for themselves. Our presentation teeth Pic 1 I. planus and I. desori. These are not the exact teeth for program. I do have a few bigger teeth but these were in my desk as I am doing this lol Pic 2 Our 5.08 inch Megalodon tooth and the tooth that I suspect will be the most popular in the presentation. Not the prettiest nor the biggest but it is still a really big tooth to me. We also use a 3 inch tooth for the presentation but I did not photograph it. Pic 3 a 2 inch hastalis, a 2.5 inch hastalis, and one that I personally think is cooler than even Megalodon, a 2.54 inch Great White. It is blue. It just looks cool and I think 2.54 is pretty large for a white shark tooth. We wrap it up with questions from the kids while we go around the classroom handing out shark teeth to the students. If you happened to read all of these, you are a good soul because these are long winded posts I know lol Thank you to all who commented and offered encouragement. I will probably start putting up the marine mammal stuff next.

This was a prep I've last year, but for some reason I've never posted it on the forum. So I thought I might change that. Last year I was fortunate enough to take a visit to the Ernst Quarries and dig for some shark teeth. Although most of the fossil I've taken home are either bones, four partial regular-sized teeth, and mostly tiny partials (some of which I accidentally damaged while digging ), the biggest find of the day was this large Cosmopolitodus hastalis tooth with its crown partially sticking out of the matrix. When Rob noticed the tooth, he initially estimated it to be ~2 inches long and insisted that I keep the tooth in the matrix, saying something like "The tooth itself is worth about $15. If you keep the tooth in the matrix, it'll be worth $60". Although my reason for visiting the Ernst Quarries was to find shark teeth to keep rather than to sell, I for some reason decided to keep the tooth in the matrix. However, I still had to prep this baby when I got home! Below is the tooth how I found it. This was going to be my first (and so far only considerate) prep I've ever done. Rob told me that the matrix can easily be scratched away using a fingernail and so taking his words and some advice I've gotten from the forum regarding something else, I grabbed one of my mom's needles and started quite literally digging off the siltstone. After around 10 minutes, a perfect root base showed up. This tooth is obviously going to be a perfect whole, so you just gotta keep scraping off the matrix. One really helpful thing I've realized at this point is that the needle I was using was perfect for such beginner's prep- it was strong enough to remove matrix effectively but not enough to do any damage to the tooth itself.

Hi everybody, it's been a long time since I've written something on the forum but I read the different thread pretty much every day. Observing in the shadow like Batman but without money, a cool costume and with an hernia just like every fellow 21 yo. However I've recently acquired a Carcharodon sp. tooth from Bahia Iglesia, labelled as an C. hastals with some sort of serration. From what I've read serration in this species might indicate some sort of patology/transitional form. In this case the cusplets/serrations are pretty much symmetrical on both side of the crown so I'm leading toward the second option. So, is this a transitional form of C. hastalis or an early C. hubbelli ? How can I distinguish between the two when the diagnostic characters aren't so obvious? I've also read that tooth from both species tend to have different characteristic if collected from different sites (like a C. hubbelli tooth where the serrations are just barely visible on the enamel) so I'm very confused. Last question: Teeth where the serrations are confined in small part of the enamel are linked just to early C. hubbelli (obviously if belonging to this specie) or is more related to individual differences into the population as a whole? Thanks to all for the answers.

Good day to everyone! Thought I’d share some the teeth found on Milnerton and Big Bay beach here in South Africa. Any help identifying would be appreciated - I’m still relatively new so the more worn and broken teeth have me clueless. More pictures to follow!

Why are t-rex teeth so expensive compared to carcharodontosaurus teeth, are they alot rarer?
